I was developing this application from a year and working
every day wth it.
Updated to the new XCode Version 7.3.
When I tried to save and exit XCode, got this error:
Failed to save MyProject.xcodeproj. Unknown error.
Then tried to change and save another file and got an error:
The document *** could not be saved, You don't have
permission.
I do have read/write permissions.
I can build and install on device.
Tried to exit again. Got the same error.
Also when I try to create new project with my Team ID.
Can build and install on device but when try to exit got the same error - cannot save it.
